When you spend €750 on a premium wireless guitar system, it is infuriating when a cheap (and unique) cable renders the whole system useless mid tour. Just weeks after purchase.
I was 7 dates into a European Tour and had to leave this wireless system in the truck and go back to using guitar cables. The supplied Sennheiser cable which connects your guitar to the wireless pack is the cheapest of the cheap.
A tech in one of the venues tried to help me, and told me about these Sennheiser packs: "The units are great, but the first thing we do when we buy them is bin the cable and install a LEMO 3 connection."
This is not good enough, not at €750. There are guitar wireless options for €100-300, I would expect cheap corner-cutting with such systems. Not a top of the range Sennheiser system.
Anyone buying this unit, do yourself a favour and buy a spare cable at the same time.
